Mother in law going against me

Brittany

So currently we live with my in laws while we wait for everything for our house to close. Our lease was up at our apartment and we didn’t want to renew or pay month to month because it was 1800 a month. We decided to move in upstairs since it’s empty. We have a 10 month old daughter and baby #2 on the way. Sometimes my daughter will be in her walker downstairs with my fiancé and I. My mother in law on numerous occasions has given her food she’s can’t have due to her being born with gastroschesis and having a very very sensitive stomach. The other day MIL had beans and she was like “ oh mila wants some “ I said “ she can’t have beans it causes her to have really bad gas and she won’t be able to sleep “ ( it was around 5:30 pm her bed time is 7:30 pm) I continued with “ she could have her gerber or fruit and baby cookies “ she rolled her eyes and like 2-3 minutes later she gave her beans. Which then caused my daughter to have gas and she kept waking up and crying from being uncomfortable or having stomach pains. Until 11pm when she was able to pass a bowel movement after I gave her gripe water. Another time I was feeding my daughter baby yogurt and MIL comes and shows my daughter a chips ahoy cookie so my daughter starts crying and refuses to eat her yogurt because she wants the cookie. Yeah she could have a little but she could have waited until I was done feeding her. My fiancé was just like “ let her have the cookie it’s fine “ like ???????? It’s gonna ruin the whole schedule for later. Another time MIL was giving my daughter coffee (with milk) and sweet bread. After I told her she couldn’t have that. Which once again made my daughter have gas all night and guess who had to stay up with her dealing with it until she was comfortable enough from her belly to be able to sleep??? ME! I told my fiancé already to talk to her about it, he says he will but he hasn’t. If I say ANYTHING to her she gets all butt hurt and tells my fiancé’s sisters then they give me dirty looks and talk shit to me and about me behind my back. It’s just ridiculous. My family asks me before they give her anything because they know how sensitive her stomach is. Not once have they given her something without asking, ( unless it’s her gerber or baby snacks) I’m not trying to be a bitch about it I’m just looking out for what’s best for my child. Then MIL will be like “ well Sam can have this why can’t mila? “ (Sam is my fiancé’s sister’s daughter that is 15 months old) like what don’t you understand that mila had gastroschesis surgery at birth and her stomach can’t tolerate or digest certain things. Like the corn on the cob she gave her yesterday, after I took it away from my daughter she comes out of the kitchen with ANOTHER piece of corn on the cob. I honestly don’t know what to do. My fiancé doesn’t say shit about it and if I say anything to her that’s slightly not in her favor she makes a big ass deal about it and all hell breaks loose.
